Now he is taking his revenge, in a brutal game that allows him to have one of his former tormentors killed each morning.
However, Sakura--a lonely, quiet, orphan girl--does not understand why she is there, unless it was due to her inaction in stopping the bullying of others. She's also the only one who received an invitation, while the others were abducted or tricked into attending. What is the final purpose of this game?
